CROSS-CONVEYER FOR SEPARATORS, 860.

SPECIFICATION forming part of Letters Patent No. 728,460, dated May 19, 1903. Vimplication filed January 7l 1903. Serial No.138,116. (No model.) i

To @ZZ whom tm/ay concern:

Be it known that I, STAcY B. HART, a citizen of the United States of America, residing at Peoria, county of Peoria, and State of Illinois, have invented certain new and useful vclass of devices which are usually positioned upon the top of the machine and receive the grain delivered therefrom and by simple mechanism are arranged to deliver the grain to either side of the 'machine at will.

The object is to produce a simple, effective, and durable device for the purpose stated.

To this end` myinvontion consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims. l

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a top plan of my improvementwith parts broken away to show the coustruction. Fig. 2 is a side elevation. Fig. 3 is a vertical section of the same in line 3 3 of Fig. 5. Fig. 4 is a section in line 4 4 of Fig. 6. Fig. 5 is a partial central vertical section showing the adjustable wings adj usted to transport the grain in one direction. Fig. 6 isa similar view showing the wings adjusted to transport the grain in the reverse direc- Fig. 7 is a detail view of the reversing mechanism and reversible wings. Fig. 8 is a detail view of the shifting mechanism. Fig.

9 is a detailview of one of the reversible wings, and Fig. 10 is a view of a slightlymodified form ot' the device.

In the drawings, l represents a conveyertube adapted to be placed transversely upon the top of a separator or equivalent machine and provided with suitable means for receiving the grain from the machine. As shown in the drawings, a hop-per Zis provided for this purpose. j

3 3 are suitable spouts at each end of the tube for conveying the grain therefrom.4 In

the preferred form the hopper `2 is placed at or near one end of the device, which end is also provided with a valve 4, adapted to close the entrance 5 to spout 3.

As thus far described my improvement isA of the usual form and construction, which is generally supplied with a centrally-supported shaft carrying a worm-conveyer and adapted to convey the grain in one direction. In my improvement means are lprovided to reverse the lead or inclination of the worm. This may be done in any preferred manner. As

shown, two parallel bars 6 6 are arranged in lieu of said shaft and may extend the entire length of the tube, as shown in Fig. 10, or, as in the preferred form shown in the other figures of the drawings, extend only part way, the

balance of the distance being completed with.

the usual shaft and Worm-conveyor. In the preferred form, as stated, the usual shaft7, provided with the Vworm-conveyer 8, extends from one end of the conveyer toward the other to a point near the hopper 2, as clearly shown in Figs. 1, 2, 5, 6.

9 is a bearing for the inner end of said shaft 7 and also for the proximate ends of the bars 6 6, as shown, the said bars and shaft being so connected as to rotate inunison.

10 10 are Wings forming, substantially, the I half of a circle, pivotally supported at their centers to the bars 6 6, as shown in Fig. 7.

The wings are suitably spaced apart, so that nately extending in opposite directions to engage, the extensions 12 of the several wings. It will thus be seen as the rod 13 is longitudinally moved the severalwings will be rotated on their pivotalv centers 11 to reverse the direction of their inclination, as clearly ICO shown in Figs. 5, 6 and more particularly shown in Fig. 7. It will thus be seen that whilel the Ashaft 7 and the bars 6 6 are so secured and attached as to be rotated in unison, so that the worm 8 will continue to transferthe grain in one direction only, that portion of the device carried by the parallel bars 6 6 may be operated to adjust the inclination of the wings forming the worm, so that the grain will be transported in the general direction of the worin 8 and delivered thereto to be delivered to the opposite end ofthe device, or they may be reversed and the grain be transported in the opposite direction and delivered to the spout 3 near the hopper 2.

15 is a sprocket-wheel secured upon the end of the shaft or extensions 6 6 for rotating the shaft, the same being driven by anysuitable connection with adriven part of the machine. Any suitable means may be employed for operating the pivoted wings 10, as described. In the preferred form such means will be extended so that the operator may control the same from either side of the separator-that is to say, from either end of the conveyer. As shown in thedrawings, this is readily accomplished in the following manner: 16 is an extending arm serving as a support for the lever 17, pivotally connected thereto, which lever has one end engaging the movable rod 13 and the other end extended to loosely engage the movable bar 18, which preferably extends the full length of the tube, as shown.

The bar 18 is also connected` with the valve 4, so that the initial movement of saidA bar will preferably first close or open the valve 4 before changing the inclination of the worm. In the preferred form the bar is connected with said valve, as at 19, Fig. 1, and has upon it two shoulders or sleeves 20 2 1, suitably arran ged to permit the valve to be substantially closed or opened before the proper sleeve contacts with the lever 17. Thus, as shown in Fig. 1, the rod 18 may be moved to the left until the shoulder 20 contacts with the end of the lever 17, the distance or lost motion being suicient to substantially close the valve 4 before reversing the worm, as before set forth. While in this position, the valve being closed, the wings are so inclined as to deliver the grain to the worm 8, which transfers it to the opposite end of the conveyer, delivering it upon the opposite side of the machine, the parts being in the position substantially as shown in Fig. 6. To reverse the device, the bar or rod 18 is longitudinally moved until the shoulder orstop 2l con tracts with the lever 17, operating the same and longitudinally moving the rod or bar 13, and thus the wings, as before set fortll. 'lhe initial movement, however, of the rod 18, as shown, serves to open the valve 4, so that there will be no obstruction to or interference with the delivery of the grain to the spout and a free discharge therefrom.

It is obvious that if desired the construction shown in Fig. 10 may be employed, in which the parallel bars 6 6 extend substantially the full length of the conveyor-tube, taking the place of the usual shaft, and the worm be entirely composed of the adjustable wings 10 10. However, this is an obvious equivalent, and the construction first described is preferred.

By the term shaft in the claims I wish to be understood as including the usual shaft or its equivalent for the purpose which, as shown, comprises the parallel bars or equivalent means. So, also, in the term worm I wish to be understood as meaning the usual continuous extending ribbon or Worm or the equivalent wings for the same purpose.

It is obvious that after having thus described my improvement various immaterial modifications may be made without departing` from the spirit of my invention. Hence I do not wish to be understood as limiting myself lo the exact form and construction shown. y
